+ * Date: 26 November 2000
+ *
+ *
+ * SUMMARY: Passing (RegExp object, flag) to RegExp() function.
+ * This test arose from Bugzilla bug 61266. The ECMA3 section is:      
+ *
+ * 15.10.3 The RegExp Constructor Called as a Function
+ *
+ *   15.10.3.1 RegExp(pattern, flags)
+ *
+ *   If pattern is an object R whose [[Class]] property is "RegExp"
+ *   and flags is undefined, then return R unchanged.  Otherwise 
+ *   call the RegExp constructor (section 15.10.4.1),  passing it the
+ *   pattern and flags arguments and return  the object constructed
+ *   by that constructor.
+ *
+ *
+ * The current test will check the first scenario outlined above:
+ *
+ *   "pattern" is itself a RegExp object R
+ *   "flags" is undefined
+ *
+ * The flags parameter will be undefined in the sense of not being
+ * provided. We check that RegExp(R) returns R  -
